【Abstract】 Purpose:The aim is to establish a rapid and precise method for the determination of chondroitin sul fate.Methods:The samples of chondroitin sulfate were determined by s pectrophotometry,based on the reaction of chondroitin sulfate with a mineral aci d-containing phlorglucinol solution.Results:Absorbance value at 558 nm obeys linear within the concentration range from 0.10 to 1.0 mg/ml,and the results were precise and accurate.Conclusion:The method is simple i n operation and has a good precision and an adequate selectivity.更多还原
